摘　　要：随着工程建设的快速发展,在既有构筑物附近进行新建工程设计施工已经成为趋势和普遍现象。乌鲁木齐外环线扩容改建工程穿越蜘蛛山设置新建隧道。新建蜘蛛山隧道与既有蜘蛛山隧道平行布置,且距离较近,属于平行小净距隧道。该文针对新建蜘蛛山隧道的隧址选择、内轮廓设计、衬砌选型、防排水设计、施工工法、爆破振速控制等方面的设计进行介绍,可为类似工程设计、施工和研究提供一定的参考。With the fast development of engineering construction,the new design and construction of engineering project near the existing buildings have become the tendency and universal phenomenon.A tunnel is newly constructed to pass through Zhizhu Mountain in Urumqi Outer Ring Line Extension Project.The newly constructed Zhizhu Mountain Tunnel is arranged parallel with the existing Zhizhu Mountain Tunnel,and the distance is closer.It belongs to the parallel tunnel with small spacing.Aiming at the position selection of the newly constructed Zhizhu Mountain Tunnel,the article introduces the design of inner contour,lining selection,waterproof and drainage design,construction method,blasting vibration speed control and etc.,which can be referred for the design,construction and study of the similar projects.
